Is it a separate purchase? Or can I download it if I already bought this plugin for LB1? Because when I check my downloads now it say's Spotify.lb2 and a LB1 version. I don't see the Spotify-Premium.lb2 download in that list. But if I download Spotify.lb2 and install this extension in LB2, it crashes and gives me an error. So I am assuming this is not the correct download?
